The gcc compiler is installed and works.

I downloaded again the project (cloned it) and get the same error.
I am using OSX El Captan 10.11.4 and Xcode 7.3.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

You need to click into the guy's edit and copy paste it. The commit never got merged into the main branch.

Worked for me~

First you need check what version iPhone sdk you have，then modify the value SDK_VERSION in Rakefile.
e.g:

then i modify Rakefile like this:

Then build ok for me.
